Chemical Structure

Difluoroacetic Acid CAS 381-73-7 chemical structure

Description

Difluoroacetic Acid (CAS 381-73-7) is a high-purity analytical reference standard with the molecular formula C2H2F2O2 and a molecular weight of 96.03 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Difluoroacetic Acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 96.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Difluoroacetic Acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
